ILBB0402ER301V

Chip Ferrite Bead Overview

The ILBB0402ER301V is a multilayer ferrite bead from the Vishay Dale ILBB-0402 series, designed for surface-mount technology in the 0402 (1005 metric) package. It exhibits an impedance of 300 Ohms with a 25% tolerance at a test frequency of 100 MHz. The component supports a maximum DC current of 200 mA and has a maximum DC resistance of 800 mOhms. It operates within a temperature range of -55°C to +125°C. Physical dimensions are 1 mm in length, 0.5 mm in width, and 0.5 mm in height.

Chip Ferrite Bead Feature Summary

• Multilayer construction provides electromagnetic interference suppression in compact designs
• Nickel barrier coating eliminates silver migration for increased reliability
• Broad operating temperature range ensures performance in rugged environments

Chip Ferrite Bead Applications

• Telecommunications equipment signal line filtering
• Computer system power distribution noise reduction
• Automotive electronics under-the-hood applications

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'V' indicates lead-free composition and RoHS compliance as per manufacturer documentation. Confirm the 0402 package footprint matches the target PCB design constraints. Ensure the 200 mA current rating aligns with the circuit's operational requirements to prevent saturation or excessive heating during procurement validation.

Chip Ferrite Bead Selection Notes

Select this component when high impedance at 100 MHz is required within a minimal 0402 footprint. The 200 mA current handling capability suits low-power signal lines rather than high-current power rails. Consider the 800 mOhm DC resistance impact on voltage drop if placed in sensitive power paths. The wide temperature range makes it suitable for automotive or industrial outdoor deployments.
